1964 Olds 98 brake booster
Does anybody know what brake booster a 64/98 what fitted with back then??
I am about to get a aftermarket booster setup now, and from what I can measure I have enough space to fit a 8" single or maybe a 9" because of the inner fender. Can any of you other 1964/98 owners support me on this one??

When looking online which is what I am doing at first, I havent come by any boosters with any measurements so far, but eyeballing using fotos found here and there, I would say I will never get a dual diaphram to fit because of the inner fender..
I have roughly a 4" gab from firewall to inner fender 4" from center of where the booster is fitted to the firewall. I am guessing a dual diaphram is waaayyyy longer from firewall and ourwards.
Honestly, I have never had one in my hands, And have only seen them in other cars, and remember sticking quiet a bit out horisontal.
That said... it is possible to get a universal slimline 9" single that is claimed to be more powerfull than a 7" dual and 8" single. http://www.ebay.com/itm/Universal-9-...item2ed90826ad
I have just removed a 8" single from a possible european car... it did a good just, so I guess it can not get any worse :-)

They can claim whatever they want - math doesn't lie. The booster force is simply diaphragm area times air pressure. The air pressure is the same for both, so area is all that matters. A 7" booster is about 38.5 square inches (ignoring the area of the actuation valve in the center of the diaphragm). An 8" booster is about 50 sq in, or about 30% more power assist. A 9" booster is over 63.5 sq in, or 65% more assist as compared to the 7". A 7" dual diaphragm booster has 77 sq in, which is obviously double the 7" single and 20% more assist than the single 9" booster.
I better get some measurement on some of those boosters, then it will be much easyer to decide.
Thank you Joe
